That was actually something that was done for the 4e Blue Dragon. They were changed to primarily inhabit stormy coastlines instead of the deserts (with Brown Dragons becoming them primary desert dwelling Chromatic Dragon), and making them rivals of Bronze Dragons. They were changed back to their original habitat in 5e.
It's a shame that WotC backtracked on a lot of the amazing lore changes that they made in 4e.I didn't remember that. 4e did try to have a lot of things make more sense
